qt5base-lts/tests/auto/widgets/dialogs/qmessagebox/tst_qmessagebox.cpp
Thorbjørn Lund Martsum 29b2506e8c Allow disable native messagebox dialog 
The native style may not match the program style and it
makes sense to give an option rather than forcing native style.

Before it could only be done with setting AA_DontUseNativeDialogs
on the app, but it is reasonable to use native file dialogs and
Qt styled messageboxes - and it is extremely cumbersome - especially
since messageboxes often can start save dialogs.

It can look a bit strange that these introduced options has just one
option (DontUseNativeDialog) and four functions, but this way it works
similar to QColorDialog, QFileDialog and QFontDialog.

[ChangeLog][QWidgets][QMessageBox] Added options functionality to
QMessagebox. The currently only option available is DontUseNativeDialog.
